What is the area of the circumference of a circle with diameter 7 yd?
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
What is the formula to calculate the area of a circle?
*=multiplication symbol /=division symbol r*(r*ㅠ)=r2 ......... radius*(radius*pi)=radius2 ........... radius times the radius times pi equals radius squared HINT HINT HINT an easier way to put this is .......... d*ㅠ/2=n ............. diameter*ㅠ/2=answer .......... diameter times pi divided by two equals the answer
Who popularized the Pi symbol?
The symbol for pi (π) has been used in mathematics for centuries to represent the ratio of a circle's circumference to its diameter. The use of the symbol π to represent this ratio was popularized by the Welsh mathematician William Jones in 1706. Jones introduced the symbol in his book "Synopsis Palmariorum Matheseos," where he used π as an abbreviation for "periphery." Over time, the symbol became widely adopted in mathematical literature and is now universally recognized as representing the mathematical constant pi.
Does a half circle have vertices?
Not necessarily. If it is a semicircle - a circle bounded by an arc and the diameter of the original circle, it has two vertices - at the end of the diameter. However, a half circle need not have a side that is a straight line. It can be like the yin-yang symbol (see link). The half circle here has no vertex.
What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
